Updated answer:
Things changed a little bit, as the previously needed dependency – ViewModelProviders – got deprecated (see the old answer for details). You can now use the ViewModelProvider constructor directly.
So, in this case, the answer would be:
private val viewModel = ViewModelProvider(this).get(SheduleViewModel::class.java)
Note that, however, if you include the androidx.activity:activity-ktx:$Version dependency (a few of the commonly used AndroidX dependencies already include it for you), you can make use of property delegation:
private val viewModel: SheduleViewModel by viewModels()
Which internally will use ViewModelProvider and scope your ViewModel to your Activity. It’s just a more concise way of writing the same thing. You can do the same for a Fragment by including the androidx.fragment:fragment-ktx:$Version dependency instead (again, commonly already included by other AndroidX dependencies).
Both the ViewModelProvider constructor and by viewModels() also accept a factory as a parameter (useful for injecting your ViewModel):
private val viewModel =
ViewModelProvider(this, viewModelFactory).get(SheduleViewModel::class.java)
and
private val viewModel: SheduleViewModel by viewModels { viewModelFactory }
Use the one that best suits you.
Old answer:
Add the androidx.lifecycle:lifecycle-extensions:$lifecycleExtensionsVersion dependency in order to import ViewModelProviders.
